IRC Log for 2012-07-17

Timestamps are in GMT/BST.

[0:00] <gordonDrogon> the key thing for me is the -ldross - dross is my own 'wiring' library.
[0:00] * BlackWabi (~wabi@c-193f72d5.133-103-64736c10.cust.bredbandsbolaget.se) Quit (Quit: reboot)
[0:00] <gordonDrogon> you could make your own library by compilng all the files under arduino/hardware/arduino/core/arduino though.
[0:00] <gordonDrogon> but I write my own.
[0:00] * kcj (~casey@unaffiliated/kcj) has joined #raspberrypi
[0:00] * PiBot sets mode +v kcj
[0:01] <exo> i see. i am not fully understanding the purpose of the wiring library. you have gpio pins wired to the input/outputs of the IC?
[0:01] <exo> then your library holds that info?
[0:01] <exo> and how to send the data over
[0:03] <gordonDrogon> wiring is what arduino is all about. An Arduino is a combination of hardware and the wiring libary supplied by arduino.
[0:04] <gordonDrogon> it's a set of subroutines that lets you control the pins easily.
[0:05] <exo> gotcha
[0:06] <exo> you create your own since you don't necessarily use the arduino hardware
[0:06] <gordonDrogon> sometimes, but I created my own some years back because I wanted to do extra stuff that I found limiting in the arduino way of things - I was also being paid by someone to produce some non-gpl software... so wrote it all from scratch.
[0:07] <grzywacz> Soooo... I'm unable to change the boot vid mode on my LCD connected through a HDMI-DVI connector. I set hdmi_group=2 and hdmi_mode=35 in /boot/config.txt, but it doesn't seem to affect anything. Clues?
[0:08] <gordonDrogon> grzywacz, not from me, sorry - hdmi has always "just worked" for me ...
[0:08] * Meatballs is now known as Meatballs|Away
[0:09] <gordonDrogon> grzywacz, I presume you've worked through the tables of settings on the wiki site?
[0:09] <grzywacz> gordonDrogon, I believe so, yes.
[0:09] <Hattara-pilvi> grzywacz: manually setting resulted in VGA terminal for me, letting Pi autodetect the settings worked
[0:09] <Walther> Apparently my Pi is capable of learning
[0:09] <grzywacz> Hattara-pilvi, I'm trying the manual way because I'm getting a strange resolution by default
[0:09] * davistv_ (~davistv@ has joined #raspberrypi
[0:09] * PiBot sets mode +v davistv_
[0:09] <Walther> I set up the /etc/rc.local to have a screen ready for me on ever boot
[0:10] <davistv_> Hi everyone.
[0:10] <Walther> I've also set up an alias for "screen -rd" as caffeine
[0:10] <Walther> ...now, as I've done it enough many times, Pi can tab-complete caffeine.
[0:10] <davistv_> I'm having some trouble getting a wifi usb interface to work. I think it's to some degree my unfamiliarity with setting up network interfaces in Debian, but it seems like something isn't working correctly.
[0:11] <davistv_> Right now I can see wlan0 through iwconfig.
[0:11] <davistv_> But I can't see it under ifconfig.
[0:11] <Hattara-pilvi> davistv_: ifconfig -a
[0:11] <Hattara-pilvi> davistv_: It is probaly just "turned off" adding '-a' to ifconfig will display non active devices too
[0:11] <davistv_> Hattara-pilvi: Trying that. Taking a long time.
[0:12] <davistv_> Looks like it's stuck.
[0:12] <davistv_> The interface is a Belkin F5D7050.
[0:12] <davistv_> Which seems to be supported with the install of an additional firmware package.
[0:12] <davistv_> Which is there.
[0:13] <davistv_> ifconfig -a won't finish. Can't cntrl-C to kill it, either.
[0:13] <Hattara-pilvi> davistv_: try ifconfig wlan0 up
[0:13] <Hattara-pilvi> and see if you can then see if in ifconfig
[0:13] <davistv_> Sure, trying to get command line control back.
[0:13] * Timmmaaaayyy (~Timmmaaaa@cpe-74-73-185-27.nyc.res.rr.com) has joined #raspberrypi
[0:13] * PiBot sets mode +v Timmmaaaayyy
[0:14] <Hattara-pilvi> davistv_: open another console and ill the ifconig from there
[0:14] <Hattara-pilvi> "killall -15/-1/-9" ifconfig
[0:14] <davistv_> Had to ctl-alt-del to reboot it.
[0:14] <exo> maybe even try dmesg to see if it recognized it
[0:15] <davistv_> Ok, will try dmesg too, as soon as it reboots.
[0:16] <Walther> Hm, overclocking further from 800 -> 900 and ram 450 ->500 resulted in 10% improvement in calculating 2000 digits of pi
[0:16] <Hattara-pilvi> davistv_: Also please give us the chipset. command 'lsubs'
[0:17] <exo> looks like arealtek
[0:17] <exo> RTL8187
[0:18] * wiiguy (~fake@unaffiliated/wiiguy) Quit (Quit: I just broke my connection, but no worries, we can rebuild it. We have the technology.)
[0:18] * Kooothor (~ktr@unaffiliated/kooothor) Quit (Read error: Connection reset by peer)
[0:18] * Syliss (~Syliss@adsl-108-201-89-33.dsl.chi2ca.sbcglobal.net) Quit (Quit: Syliss)
[0:19] * Kooothor (~ktr@unaffiliated/kooothor) has joined #raspberrypi
[0:19] * PiBot sets mode +v Kooothor
[0:19] <davistv_> dmesg says: zd1211rw registered, firmware version 4725, chip 050d:705c v4810 high 00-17-3f AL2230_RF pa0 g--NS
[0:20] <exo> so it's a zydas
[0:20] <davistv_> Then it gives a couple info lines that look like it's trying to set it up (periodic_channel_available and schedule_periodic), then it gives an error:
[0:21] <davistv_> ERROR::dwc_otg_hcd_urb_enqueue:487: DWC OTG HCD URB Enqueue failed adding QTD. Error status -4008
[0:21] <exo> what does 'ifconfig wlan0 up'
[0:21] <exo> do
[0:21] <davistv_> SIOCSIFFLAGS: Unknown error 4008
[0:21] <exo> are you root?
[0:22] <davistv_> Yes.
[0:22] * Milos|Netbook (~Milos@pdpc/supporter/student/milos) Quit (Ping timeout: 260 seconds)
[0:22] <exo> just making sure :)
[0:22] <davistv_> I thought I read something about there being a problem with uploading firmware to these chipsets with the kernel that's currently being distributed.
[0:23] * Siph0n| (~Siph0n@101.sub-174-235-193.myvzw.com) has joined #raspberrypi
[0:23] * PiBot sets mode +v Siph0n|
[0:23] <exo> quite possibly, they had some kernel issues with that chipset back in like '09
[0:23] <exo> but i think they fixed it
[0:23] * mischat (~mischat@93-97-51-125.zone5.bethere.co.uk) has joined #raspberrypi
[0:23] * PiBot sets mode +v mischat
[0:24] <Hattara-pilvi> That ame error message is on RPi forums too....
[0:24] <Hattara-pilvi> davistv_: Are you running X?
[0:24] <davistv_> No.
[0:24] <davistv_> It's installed, but not running.
[0:25] <davistv_> I've also got a cheap Tenda W311U usb wifi dongle, it gives even worse results from what I remember.
[0:26] <davistv_> I've been struggling with wifi for a few days now, not sure what to do. It would suck to pay more for the wifi card for these things than the actual RPi. Is that what's necessary right now?
[0:27] * Siph0n (~Siph0n@101.sub-174-235-193.myvzw.com) Quit (Ping timeout: 246 seconds)
[0:27] <exo> ifconfig -a
[0:27] <exo> what devices does it show
[0:27] <davistv_> I disconnected the usb dongle, shows just eth0 and lo.
[0:28] <davistv_> ifconfig -a now gives a wlan0
[0:28] <davistv_> (just plugged it back in)
[0:28] <exo> k
[0:28] * MauveGnome (~MauveGnom@host-92-21-176-20.as13285.net) Quit (Quit: Leaving.)
[0:28] <Hattara-pilvi> This might be related https://github.com/raspberrypi/linux/issues/29
[0:29] <davistv_> If I do "ifconfig wlan0 up" I get SIOCSIFFLAGS: Unknown error 4008
[0:29] <exo> iwlist wlan0 scan
[0:30] <exo> (hoping you have that cmd)
[0:30] <davistv_> wlan0 Interface doesn't support scanning; Network is down
[0:30] <exo> k
[0:31] * mythos (~mythos@unaffiliated/mythos) Quit (Remote host closed the connection)
[0:31] <davistv_> So I'm not running X right now, do I need to uninstall it to avoid the problems talked about in that issue on github?
[0:32] * davistv_ is still trying to figure out what 3.1.9+ means for a kernel...
[0:32] <exo> apt-cache search zd1211
[0:32] <exo> did you install that firmware?
[0:32] <exo> (assuming you are on debian, cant remember)
[0:32] <davistv_> Yes, it shows up in apt-cache.
[0:32] <exo> have you checked this site out?
[0:33] <exo> http://omer.me/2012/04/setting-up-wireless-networks-under-debian-on-raspberry-pi/
[0:33] <davistv_> zd1211-firmware - Firmware images for the zd1211rw wireless driver
[0:33] <davistv_> Looking at that.

[0:36] * Milos|Netbook (~Milos@pdpc/supporter/student/milos) has joined #raspberrypi
[0:36] * PiBot sets mode +v Milos|Netbook
[0:37] <davistv_> I get to the part in that where it checks dmesg, but I've already got errors. Can't move on to iwlist wlan0 scan.
[0:38] <exo> hmm
[0:39] <exo> installed the package? and rebooted?
[0:40] <davistv_> It was already installed before.
[0:40] <davistv_> Rebooted many times since.
[0:40] <exo> k
[0:40] <davistv_> I'm also seeing some kernel messages about eth0:
[0:40] * Compy (~Compy@c-98-251-52-68.hsd1.ga.comcast.net) Quit (Disconnected by services)
[0:40] <exo> what do you see?
[0:40] * Compy (~Compy@c-98-251-52-68.hsd1.ga.comcast.net) has joined #raspberrypi
[0:40] * PiBot sets mode +v Compy
[0:40] <davistv_> hub 1-1.3:1.0: hub_port_status failed (err = -110)
[0:41] <davistv_> smsc95xx 1-1.1:1.0: ethos Failed to write register index 0x000000114
[0:42] <davistv_> Maybe one less 0 there.
[0:42] <davistv_> 5 0s
[0:42] <davistv_> MII is busy in smsc95xx_mdio_read
[0:43] <davistv_> Does eth0 typically give read and write errors over and over?
[0:44] <davistv_> I'm getting lots of eth0: event 4 may have been dropped.
[0:44] <exo> uninstall that package
[0:44] <exo> apt-get install firmware-ralink
[0:44] <exo> try using that package
[0:44] * Syliss (~Syliss@adsl-108-201-89-33.dsl.chi2ca.sbcglobal.net) has joined #raspberrypi
[0:44] * PiBot sets mode +v Syliss
[0:45] <davistv_> Ok, removing.
[0:47] <davistv_> Done, but I'm still getting those errors about failing to read or write eth0 registers.
[0:47] <davistv_> Normal?
[0:47] * blkhawk is now known as blkaway
[0:47] <davistv_> Haven't installed the ralink firmware package yet.
[0:48] <davistv_> Ok, it's installed now.
[0:48] <exo> reboot
[0:48] <exo> let me know when up
[0:48] <davistv_> ok
[0:49] <exo> ifconfig wlan0 up
[0:49] <exo> actually
[0:49] <exo> you have that profile setup for the device?

[0:55] <davistv_> I've tried setting it up several times, following several different methods. Not sure where it's at right now, have to look.
[0:56] <davistv_> boot log is complaining that it can't load the zd1211 firmware file.
[0:56] <TimRiker> raspbmc distro does not include vty support? ugh...

[1:02] <grzywacz> Ok, I'm confused now. Even my monitor says it's working at full resolution (1280x1024), and yet there's a black border around the image. O_o
[1:02] * TylerP223 (~IceChat9@75-136-20-51.static.jcsn.tn.charter.com) Quit (Quit: Light travels faster then sound, which is why some people appear bright, until you hear them speak)

[1:03] <JMichaelX> does anyone here have much experience ordering items shipped by China Post, and how long those shipments usually take?
[1:04] <grzywacz> plugwash, that helped, thanks

[1:10] <Syliss> JMichaelX email/message the seller asking when your items were shipped
[1:10] <Syliss> should have tracking
[1:11] <JMichaelX> Syliss: yes, they do, but traching info from china post is less that helpful.
[1:11] <Syliss> really? mine was fine
[1:11] <Syliss> from one of the same sellers too
[1:12] <JMichaelX> i have only ordered one item that was shipped by china post. it was shipped out by the vendor on june 13. i received the item on july 13.
[1:12] <JMichaelX> in the past, i mean
[1:12] <Syliss> hmm
[1:12] <JMichaelX> it sat at a china post shipping hub for several weeks.... i'm just wondering how come that is
[1:13] <ReggieUK> I've had loads of stuff via china post
[1:13] <JMichaelX> common*
[1:13] <JMichaelX> ReggieUK: and generally it didn't take so long?
[1:13] <ReggieUK> 2-4 weeks
[1:13] <ReggieUK> 5 tops (so far)
[1:13] <ReggieUK> all sorts of stuff too
[1:14] <ReggieUK> from different vendors
[1:14] * chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) Quit (Quit: Leaving)
[1:15] <JMichaelX> yea... it's not such a big deal, but 4 - 5 weeks is a fairly long time
[1:16] <ReggieUK> If I need it quick then I don't order china post stuff
[1:16] <Syliss> yeah sadly thats what happens when you order from china
[1:17] <JMichaelX> ok, that is what i was wondering about, and why i was asking
[1:17] <ReggieUK> but for the most part, anything I want from china I am happy to wait for
[1:17] <ReggieUK> then again, if they offer an expedited service, you can expect it quicker :)
[1:18] <JMichaelX> yea, that is not the case for me...
[1:18] <JMichaelX> yes, i might have been able to do that
[1:18] <ReggieUK> unfortunately, all the while the us charges a fedex/ups tax for shipping, I'll always look to china first
[1:19] <ReggieUK> if I can't source it locally that is
[1:21] <JMichaelX> yep. for many items the wait would be fine.
[1:22] * notfunk (~notfunk@ip72-221-66-218.ri.ri.cox.net) Quit (Read error: Connection reset by peer)
[1:23] <JMichaelX> i had busted the LCD in my HTC Evo 3d, and ordered a replacement that wound up being shipped china post. it took 4 weeks exactly to get here. if i had it to do over, i think i would have spent a little more, and just bought a used one on craigslist
[1:23] * nplus (~chatzilla@unaffiliated/simont) Quit (Read error: Connection reset by peer)
[1:23] <JMichaelX> but... the replacement LCD works just fine, and i'm happy now

[1:24] * PiBot sets mode +v nplus
[1:24] <JMichaelX> i received my motorola lapdock today, but am missing an adapter and 2 cables.... and hate the idea of waiting another 4 weeks until those arrive
[1:25] <JMichaelX> c'est la vie
[1:25] <ReggieUK> yeah but those things are so cheap you probably don't need to get it from china
[1:26] <JMichaelX> that might be.
[1:26] <JMichaelX> in my case, most of them would still need to be ordered... those cables and that adapter are not going to be on hand anywhere near here
[1:26] * dutchfish (~wil@unaffiliated/dutchfish) Quit (Quit: Splash, leaving the bowl)
[1:29] * Neavey (~Neavey@cpc9-aztw25-2-0-cust234.aztw.cable.virginmedia.com) Quit (Quit: Computer has gone to sleep.)
[1:29] <davistv_> exo: I'm back. ralink is installed. Complains about not being able to read the firmware file with the Belkin adapter plugged in , of course. But no complaints with the Tenda adapter. Seems to like it so far...
[1:29] <davistv_> lsusb and it shows up.
[1:30] <davistv_> iwconfig doesn't see it, though.
[1:31] <JMichaelX> davistv_: which chipset is your adapter using?
[1:31] * Siph0n| (~Siph0n@101.sub-174-235-193.myvzw.com) Quit (Read error: Connection reset by peer)

[1:32] * PiBot sets mode +v chris_99
[1:33] <Hattara-pilvi> davistv_: ifconfig -a
[1:33] <davistv_> I remember editing a file somewhere that associated the wlan0 with the chipset maybe?
[1:33] <davistv_> Not sure now.
[1:34] <Hattara-pilvi> devices are by default turned off when you plug tehm in. If config will only show devs turned on
[1:34] <davistv_> ifconfig -a doesn't show it, just eth0 and lo.
[1:34] <Hattara-pilvi> What is the dmesg output after plugging it in
[1:34] <JMichaelX> davistv_: i have a generic/no-name adapter using that chipset, and ran into the same thing. someone in this channel gave me this link: http://mitchtech.net/realtek-wireless-dongle-rt3070-on-the-raspberry-pi/
[1:34] <davistv_> New high speed usb device number 9 using dwc_otg
[1:35] <JMichaelX> davistv_: provided you are using debian, it might help you out
[1:35] <davistv_> new USB device found, idVendor=148f, idProduct=3070
[1:35] <davistv_> New USB device strings: Mfr=1, Product=2, SerialNumber=3
[1:35] <davistv_> Product: 802.11 n WLAN
[1:35] <davistv_> Manufacturer: Ralink
[1:35] <davistv_> SerialNumber: 1.0
[1:35] <davistv_> That's it.

[1:36] <davistv_> Looking at your link, JMichaelX
[1:36] <JMichaelX> davistv_: those instructions got my non-name rt3070 working
[1:36] <JMichaelX> no-name*
[1:37] <davistv_> Hm. lsmod is still showing the zd1211rw instead of ralink3070.
[1:38] <davistv_> zd* is not in /lib/firmware
[1:38] <davistv_> rt3070.bin is, though.
[1:38] <davistv_> Hm.
[1:39] <JMichaelX> davistv_: yes, read the post...
[1:39] * roivas (~scott@97-83-0-56.dhcp.aldl.mi.charter.com) has joined #raspberrypi
[1:39] * PiBot sets mode +v roivas
[1:39] <JMichaelX> or the article, i mean
[1:39] <davistv_> Ok.
[1:39] <JMichaelX> basically, you need to replace that rt3070.bin with the one specified in that article
[1:40] <JMichaelX> davistv_: IF that is indeed your chipset
[1:40] <JMichaelX> i take that back... you add rt2870.bin
[1:41] <davistv_> Ok.
[1:41] <JMichaelX> i *think* the correct firmware might be included in the non-free firmware package in wheezy
[1:41] <JMichaelX> but not in squeeze
[1:43] * chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) Quit (Quit: Leaving)
[1:43] <davistv_> rt2870.bin came with ralink-firmware, it looks.
[1:43] * muumi (~muumi@h71n4-m-sp-d1.ias.bredband.telia.com) has joined #raspberrypi
[1:43] * PiBot sets mode +v muumi
[1:45] <JMichaelX> ok, yea... ralink-firmware
[1:45] <JMichaelX> you're correct
[1:48] <JMichaelX> if you do follow the instructions in that article, please post the results to the channel
[1:48] <elspuddy_pi> dose vnc run well on a pi ?
[1:48] * int3nz0r (~int3nz0r@541A72CA.cm-5-3b.dynamic.ziggo.nl) Quit (Quit: Computer has gone to sleep.)
[1:49] <Hattara-pilvi> elspuddy_pi: It is usable
[1:49] <davistv_> I'll try restarting just with the firmware from the ralink-firmware package first.
[1:49] <JMichaelX> davistv_: yes....
[1:49] <Hattara-pilvi> elspuddy_pi: I recomend using some bare wm instead of LXDE or some other DE
[1:49] <JMichaelX> davistv_: you might also need to add 'usbcore' to /etc/modules
[1:49] <mervaka> xmonad? :)
[1:50] <JMichaelX> davistv_: i do not know for sure
[1:50] <elspuddy_pi> hattare-pilvi : usable? what are the downsides ?
[1:50] <JMichaelX> mervaka: i have never used xmonad, but have been thinking about giving it a whilr on the pi
[1:51] <JMichaelX> whirl*
[1:51] <mervaka> i use it on my laptop
[1:51] <JMichaelX> i do not know any haskell whatsoever
[1:51] <mervaka> its lovely, though you need to move your modifier key to super
[1:51] <mervaka> else irssi wont get to use alt

[1:51] <Hattara-pilvi> elspuddy_pi: I'm not sure but I think freenx is faster than vnc servers... Well in general the X11 is not super fast in RPi, so that is also seen in vnc and vnc adds some overhead of its own
[1:52] <mervaka> i dont know/care for haskell, either
[1:52] <JMichaelX> thanks for the pointer there. i have made note of that

[1:53] <aaa801> anyone going to this:? http://iseries.multiplay.co.uk/i46/tickets
[1:53] <JMichaelX> mervaka: does xmonad work pretty much out of the box for you, on the pi?
[1:53] <mervaka> plenty of tutorials on basic customisation. i just don't dislike the default layout enough to change it
[1:53] <mervaka> but yeah
[1:53] <JMichaelX> good deal
[1:53] <mervaka> just apt-get installed it, then chose it in lightdm as i logged on
[1:54] <JMichaelX> i was thinking that if a person were going to mostly use terminal apps, something like xmonad would be the way to go
[1:54] <mervaka> though the laptop runs 'buntu
[1:54] <mervaka> yeah
[1:54] <mervaka> super+shift+enter = new terminal
[1:54] <elspuddy_pi> hattare-pilvi : thanks for the info :)

[1:56] <mervaka> make sure you install dmenu too, separately
[1:56] <mervaka> explicitly, rather
[1:56] <mervaka> xmonad uses it in its default layout, but doesnt depend on it in packages
[1:57] <davistv_> Ok, reboot seemed to help.
[1:57] <davistv_> I'm now getting a list of access points back from iwlist wlan1 scan
[1:57] <JMichaelX> davistv_: it's working?
[1:57] <davistv_> it renamed wlan0 to wlan1 for some reason.
[1:57] <davistv_> Not yet, haven't gotten it configured to access our router, but it looks doable.
[1:57] <JMichaelX> yea, it might think it is now seeing a different adapter

[2:20] <davistv_> Ack.
[2:21] <davistv_> I think the last thing I'm stuck on is a weird character in the wpa.conf file.
[2:21] <davistv_> I take it backslash is not the right escape character?
[2:21] <davistv_> It's complaining that it can't parse the file.

[9:52] <Gadgetoid> Morning!
[9:53] <gordonDrogon> Yup. and there's even a big yellow thing outside too.
[9:53] <gordonDrogon> although I have to go to a clients site later this morning...
[9:53] <Gadgetoid> I am positively zombified this morning, I need to put the Arduinos elsewhere and back slowly away from them
[9:54] <gordonDrogon> :-)
[9:54] <gordonDrogon> my cut-off for bed is midnight. only very rarely do I stay up last that...

[9:55] <Gadgetoid> I seem to end up at 1am often, sometimes later
[9:55] <Gadgetoid> depends what I'm engrossed in; couple of nights ago the LCD hacking kept me up until 2 or possibly 3
[9:55] <gordonDrogon> it is rather addictive :)
[9:55] <Gadgetoid> Truth!
[9:56] <Gadgetoid> left my Pandora at home, darnit! had the Arduino IDE up and running and just needed to plug it through a USB hub to see if it'd detect and program an Arduino
[9:57] <Gadgetoid> As on the Pi, though, compiling is a little on the slow side
[9:57] <gordonDrogon> no reason why not - as long as the kernel regocnises the usb serial drivers.
[9:57] * Veryevil (~Veryevil@ has joined #raspberrypi

[9:58] <Gadgetoid> I've had the IDE running in a Chroot before, and the serial breakout detecting; but couldn't get the two to see each other. Someone's tested and packed up the IDE since then though
[9:58] <gordonDrogon> not found it too bad on the Pi, but I've not tried compiling anything more than a few 100 lines or so. My DROSS system takes under a minute to compile & create the library.

[10:01] <gordonDrogon> Hm. 2600 lines of .c and .h and it took 30 seconds to compile.
[10:02] <Gadgetoid> Hmm, seems faster than the Pandora- although the default clock is higher
[10:02] <gordonDrogon> that's makefile style compiling.
[10:02] <Mr_Sheesh> full make or incremental, though?
[10:03] <gordonDrogon> full. actually, just re-done it now it's finished doing a big copy - 5 second.
[10:03] <Mr_Sheesh> (figure full but always ASK, heh)

[10:04] <Gadgetoid> My insides are responding in protest to the disgusting amount of coffee I'm forcing into myself
[10:05] <gordonDrogon> big fry-up... although I've just had porridge, a nice latte and a slice of sourdough toast & butter...
[10:05] <Gadgetoid> deary me
[10:05] <gordonDrogon> must get round to released dross at some point too.
[10:06] <Gadgetoid> What does DROSS actually do?
[10:06] <gordonDrogon> it's a real-time task scheduller.
[10:07] <gordonDrogon> there's a central 1KHz interrupt and this can call tasks. So you get the tasks to do stuff like poll sensors, and so on.
[10:08] <gordonDrogon> then you write code to access the sensors, so you ge away from the "big loop" type of program where you call all the sensor reading stuff inside your big loop every time
[10:08] <Gadgetoid> Yeah, I'll readily admit that the big-loop style positively disgusts me :D
[10:08] <Gadgetoid> As a web programmer, I'm very used to event-driven code
[10:09] <drazyl> everything-is-a-file and select() :)
[10:09] <gordonDrogon> it was a bit of a hack to make arduino/wiring work - and more importantly work in an easy to use fashion for newbies.
[10:11] <gordonDrogon> http://unicorn.drogon.net/blink.c
[10:11] <gordonDrogon> that's the LED blink program as a dross task.
[10:12] <gordonDrogon> it's created in the main program with: newDrossTask (blinky, 0, "blinky") ;
[10:12] <gordonDrogon> the "blinky" in quotes is stored if debugging is enabled and there's a "ps" type function you can call to give stats, etc.
[10:12] <gordonDrogon> the 0 means the task is self-schedulling, if > 0 then the task is called exactly that many mS.
[10:12] <Gadgetoid> Waaa...
[10:13] <Gadgetoid> blink is defined in the scope of the task blinky, how, what??? when??? where?
[10:14] <gordonDrogon> blink is a static variable inside the function.

[10:14] <gordonDrogon> DROSS_TASK is jus a macro that defines a function with an extra hidden parameter.
[10:14] <Gadgetoid> gordonDrogon: yeah??? but??? how??? do static variables maintain their state within a function across discrete function calls?
[10:15] <gordonDrogon> the 'static' part tells it to do that.
[10:15] <Gadgetoid> Ah, I'm learning things
[10:15] <gordonDrogon> a variable declared as static inside a function retains its value for the lifetime of the program.
[10:15] <gordonDrogon> and it's initialised to zero too.
[10:15] <gordonDrogon> so that saves a step and a few bytes of code.
[10:15] <Gadgetoid> I really should read some more C basics
[10:16] <gordonDrogon> the compiler does all that for you.
[10:16] <gordonDrogon> have you found out about volatile variable yet?
[10:16] <Gadgetoid> I'm vaguely aware of the difference
[10:16] <gordonDrogon> ok you'll need to know if you get into concurrent/interrupt driven stuff.
[10:16] <Gadgetoid> volatile to tell the compiler that a variable is subject to sudden changes- ie: an interrupt could be changing it whilst the main program flow is working on it
[10:17] <Gadgetoid> But one would logically pass the volatile variable's current state into a working variable if the code was not tolerant of sudden changes?
[10:18] <Gadgetoid> Ahhh this takes me back to the days of learning *shudder* ASP
[10:19] <gordonDrogon> essentially if a variable can be modified outside normal program flow (ie. in an interrupt routine) then you need to declare it volatile.
[10:19] <gordonDrogon> yes, you can take a copy.
[10:20] * soldicon (~soldicon@unaffiliated/soldicon) Quit (Quit: leaving)
[10:20] <gordonDrogon> essential if it's a multi-byte variable too - take a copy with interrupts turned off...
[10:20] <gordonDrogon> so it doesn't change half way ...
[10:20] <Gadgetoid> Good grief, didn't even think of that
[10:21] <Draylor> thats why you'll learn to love C
[10:21] <gordonDrogon> good job you'r not programming the next space shuttle then ;-)
[10:21] <drazyl> and don't cache it in a register ...
[10:21] <Draylor> either you think of it, or it'll kick your rear and make you wish you had :)
[10:21] <Gadgetoid> Draylor: haha, I seem to be scraping by with messy hacks thus far, but what I'm doing isn't very complex
[10:22] <gordonDrogon> most compilers are better than you (or me) are at picking register variables these days (or they ought to be!)
[10:22] <Gadgetoid> The next challenge I've set for myself, to get away from trying to do image compression, is to re-create a 4-character, 7-segment display procedurally on my LCD
[10:22] <gordonDrogon> can you draw lines and plot points?
[10:23] <Gadgetoid> gordonDrogon: Yeah, I nicked the line drawing/pixel plotting stuff from an existing library to get me started
[10:23] <gordonDrogon> ok.
[10:23] <Gadgetoid> And the display buffer stuff, to boot, although the awesome double buffering is my own
[10:24] <gordonDrogon> :)
[10:24] <Gadgetoid> By awesome, I mean: about 3 lines of code, simple, but it makes me feel good about myself anyway
[10:24] <gordonDrogon> not had time to hook up my litle 128x64 LCD yet. maybe tonight when I get back from client.
[10:24] <Gadgetoid> trouble with 128x64 is that it's too big :(

[10:25] <Gadgetoid> The beauty of 84*48 is that you can buffer it twice in 1008 bytes
[10:26] <Gadgetoid> Then before drawing a segment of the LCD (1 column * 8 rows ) you can check to see if it's actually changed by comparing the two buffers
[10:26] <Gadgetoid> Net result: call UpdateLcd frequently and animate the hell out of stuff

[10:52] * Tachyon` rolls eyes
[10:52] <Tachyon`> it's up to the purchaser to decide what to do with it, none of your damn business
[10:52] <Tachyon`> yes, I'd like everyone who has one to be developing for it but that's never going to happen, lol
[10:53] <Gadgetoid> That would be true, if said purchaser would keep their disgusting offences to themselves and cease filling the community with whining when it doesn't work in the specific way they fabricated entirely in their imagination
[10:53] <Tachyon`> oh, right, that -.-
[10:54] <Tachyon`> fair enough, lol
[10:54] <reider59> I say let people do what their needs dictate. I can use the Pi to program Python, later learn C and maybe more. I can play with my LCD to my hearts content. When I feel like it I can pop in another SD Card and use it as a Media Centre. For those who just want to do that well that`s the choice they make. It`s all things to all people
[10:55] <Gadgetoid> I just dislike people leaching on the community and filling it with self-entitled whining, it's very damaging and often discourages developers??? it's worse in the jailbreaking world than it is here, though, so I should be thankful for that at least!
[10:55] <Tachyon`> I want to use mine for robotics and for setting up a few in a cluster and I've had a bollocking in here for /that/ in the past for not using GPUs so people can be a bit fixed in their ideas of what they should be used for
[10:55] <Gadgetoid> By and large, the Pi bunch are a great lot
[10:55] <rm> the "Media centre" crowd needs to pull their heads out of their somewhere, and notice 100500 models of $50-$70 chinese Android media centres
[10:55] <Tachyon`> ah, too much noise,. not enough signal?
[10:55] <rm> readily available for order
[10:55] <cmug> Thats why I bought 2 Pi's, one to integrate to my TV and the other one for the benefitial stuff
[10:55] <Tachyon`> can't you move the media centre discussion elsewhere?
[10:55] <Tachyon`> have somewhere dedicated for that
[10:55] <Squirm> am going to end up creating a R/C car, through wifi. though don't know where I'm going to start at the moment and the idea isn't that original. but it'll be interesting
[10:55] <Gadgetoid> rm: Yeah, there's that. I don't quite understand what people see in the Pi as a media centre??? it's not well suited at all
[10:56] <buZz> hehe exactly
[10:56] <buZz> ppl going 'omg xbmc runs on raspi' make me wanna facepalm
[10:56] <Squirm> well, actually my Pi might end up doing everything, Media Center, File Server R/C car controller, Thermometer
[10:56] <Tachyon`> I think they'll be great for robotics
[10:56] <Tachyon`> they're just so small/light/power efficient
[10:56] <buZz> they are not efficient
[10:56] <Gadgetoid> Squirm: go for it!
[10:56] <Tachyon`> <=8W
[10:56] <Tachyon`> that's pretty bloody efficient
[10:57] <Tachyon`> for a linux box
[10:57] <buZz> Tachyon`: you can drop it about 20% with a small mod
[10:57] <booyaa> i totally want to do the whole near space stuff
[10:57] <Gadgetoid> The Pi brings a pretty good brain to the mix, but I'd still want an Arduino to handle the load
[10:57] <Tachyon`> given the old linux box I ran here drew about 250W
[10:57] <buZz> hehe
[10:57] <Tachyon`> I think I'll take the 8 as it is

Plus what you do is right for you at this moment in time, your needs may change later. but if people alienate you by giving you flak now then it`s much less likely. We also, respectfully, need to remember we aren`t just seeing people with a lot of experience using Linux, the Pi, Python, C, LCD so they are bound to raise concerns at some point.
[10:57] <Tachyon`> so pi and servos will go for quite some time

[10:59] <Gadgetoid> Squirm: the Pi got me into Arduino, and I've neglected the Pi since??? haha, but hopefully the Arduino addiction will die down soon and I'll find the time to commit back to maintaining my wrappers for WiringPi
[10:59] <Tachyon`> that'll work really well once it gains support for it
[10:59] <buZz> and a 1cm wide CRT ;)

[11:03] <Tachyon`> like not being able to see the environment through them

[11:03] <Tachyon`> like you can with glass
[11:03] <Tachyon`> that's important to me
[11:03] <buZz> there is a look-through Vuzix screen aswell
[11:03] <Tachyon`> I was originally considering the vuzix wrap 920
[11:03] <Tachyon`> but although those look see through, they aren't

[11:03] <Gadgetoid> If research into blindness has taught us anything, it's that we don't need a physical display to feed visual information into our brains
[11:03] <Tachyon`> that is the wrap 920!
[11:03] <Gadgetoid> But that doesn't stop stuff like that being cool!
[11:03] <buZz> Tachyon`: this is the wrap 920 AR
[11:03] <reider59> I`d like to see virtual screens become more of a reality too
[11:04] <Tachyon`> oh yes
[11:04] <Tachyon`> I discounted the 920AR because they'd make me look like a pillock and it's only 640x480 cameras
[11:04] <buZz> hehe
[11:04] <buZz> 640x480 is pretty high for this tech

[11:05] <Tachyon`> yeah, I don't have one of those yet, my mechanical skills are extremely limited
[11:06] <buZz> as are mine
[11:06] <Tachyon`> I was wondering if the pi could replace both the computer and the controller board
[11:06] <buZz> but growing fazt
[11:06] <Tachyon`> but apparently it can't
[11:06] <buZz> no
[11:06] <Tachyon`> as it doesn't have a real time kernell
[11:06] <buZz> pi is too slow
[11:06] <reider59> GPS was really designated Military Use but the public gets to use it because they don`t want a load of commercial ones up possibly spying on them too. these things happen in time and moods change.
[11:06] <buZz> doesnt need realtime kernel
[11:06] <buZz> but pi is just WAY too slow
[11:06] <buZz> slicing a 3d object takes a lot of math
[11:06] <buZz> raspi can do it
[11:06] <buZz> but it will take > 1 day
[11:06] <Tachyon`> the pi has an FPU doesn't it?
[11:06] <buZz> yeah, barely
[11:06] <Tachyon`> just with limited support as yet

[11:11] <Tachyon`> ah, a drone for search and rescue
[11:14] <Squirm> Gadgetoid: was afk. why not get your wiring Pi interface with Arduino using the GPIO?
[11:15] <Gadgetoid> Squirm: serial works well, as you can even do it over USB and forego the GPIO entirely
[11:15] <reider59> Probably because the arduino is 5v and runs OK via USB but the GPIO pins are 3.3V tolerant.
[11:15] <buZz> actually
[11:15] * Maccer (~Maccer@ Quit (Excess Flood)
[11:15] <Gadgetoid> My Arduinos are 3.3v :D
[11:15] <buZz> you can run an arduino on 3.3v aswell ;)
[11:16] <buZz> to get IO on 3.3v
[11:16] <Squirm> Gadgetoid: the GPIO scares me. I want to learn how to use it, though I have no idea where to start. bought myself a LM35 thermometer, though I don't really know how to start interfacing it
[11:16] <reider59> ahhh, was it the older ones that were 3.3?
[11:16] <buZz> no, _all_
[11:16] <Gadgetoid> As I built them on a breadboard, rather than buying them
[11:16] <buZz> there is no fixed voltage for them
[11:16] <reider59> gotcha
[11:16] <Gadgetoid> At 16Mhz they have a brownout of ~2.7v or something like that
[11:17] <Gadgetoid> So 3.3v is actually pretty comfortable, despite being out of spec (4.5v is the lowest for 16mhz iirc)

[11:29] <gordonDrogon> hi
[11:29] <gordonDrogon> Squirm, that LM35 won't work directly on a Pi I'm afraid...
[11:29] <buZz> maybe we should just shoehorn his hack into libc
[11:30] <urs> buZz: if you add this lib to /etc/ld.so.preload (probably need to create that file), it is loaded by default and overrides libc's implementation
[11:30] <urs> => drop-in replacement
[11:30] <Squirm> gordonDrogon: how much more would I need to do to get it to interface?
[11:30] <buZz> ah nice
[11:31] <gordonDrogon> Squirm, well - it's analog, so you need an analog to digital convertor - e.g. an Arduino ..
[11:31] <gordonDrogon> Squirm, although that's overkill...
[11:31] <gordonDrogon> Squirm, the Gert board also has A/D on-board which I've not used yet - but will soon.

[11:36] <Gadgetoid> smikey: what touch screen?
[11:36] <Squirm> gordonDrogon: yeah, I saw that image looking for help on what I wanted to do
[11:36] <Gadgetoid> And, yes, you only want to be putting 3.3v logic into the Pi
[11:37] <Gadgetoid> Some of the touch screens I've seen work by taking a current across 2 pins, and outputting a variable voltage from another, then flipping to get X/Y values separately??? ie: they're glorified variable resistors which the Pi would not be able to directly read
[11:37] <Squirm> Gadgetoid: I've actually bought a Micro Maestro, a usb servo controller. the I/O on the controller can handle digital/analog. so I'll actually be able to use that

[11:39] <Gadgetoid> smikey: And I quoth: "Readings are taken by putting 5V across two of the pins and doing an analog to digital conversion on the other two pins."
[11:39] <Gadgetoid> If you're doing an analog to digital conversion, then you can handle the logic level issue there and make sure whatever converter you use talks the Pi's voltage

[12:28] <Gadgetoid> deafanon: overwhelming number of 1 star reviews suggest; no
[12:29] <Gadgetoid> People's mileage seems to vary when it comes to Pi power supply, but ultimately you want something that will deliver ~1A with a consistent 5v supply voltage
[12:29] <deafanon> Gadgetoid: I have plenty of original 9300 chargers from RIM, was hoping I'd be able to use them with the rPi
[12:30] <Gadgetoid> deafanon: what sort of oomph do they provide? I'd guess 1A to 1.2A?
[12:30] <Arch-MBP> deafanon: while i was able to use one of those myself it wasn???t very stable when you start to add more stuff
[12:30] <Arch-MBP> Gadgetoid: mine was a 850mA BUT didn???t meet the required volts betweens tp1 and tp2

[12:48] <Gadgetoid> hetii: If you need to ask, it's not something you should be doing
[12:49] <dutchfish> deafanon, do you self a feavor and get a 5V 1A from the list
[12:49] <Arch-MBP> Gadgetoid: lol
[12:49] <Gadgetoid> That's the golden rule of overclocking...

[12:49] <Arch-MBP> that???s the rule for fight club
[12:50] <Arch-MBP> hetii: use the values at the bottom of that grid
[12:50] <Arch-MBP> that???s what im using
[12:50] <hetii> ok thx.
[12:50] <dutchfish> tip for overclockers: if you worried about stability, stat you ntp jitter and find out.
[12:50] <Gadgetoid> Arch-MBP: Cruel....
[12:50] <hetii> did someone use liquid azote to for cooling ?
[12:50] <hetii> and test the maximum ?
[12:51] <Gadgetoid> The "Warranty will be voided if overvoltage is used." bit in bold should probably be read several times over

[12:52] <dutchfish> Gadgetoid, maube some bit
[12:52] <Gadgetoid> dutchfish: probably! but I have no idea how
[12:52] <dutchfish> deafanon, yw
[12:52] <Arch-MBP> liquid cooling? that???s going a little overboard
[12:53] <booyaa> ah shoot let him

[12:59] <Chetic> is it safe to unplug the RPi at any time, running debian squeeze? is there some kind of low voltage handling to prevent corruption on the sd card?
[12:59] <booyaa> if possible it's better to issue a halt first
[13:00] <dutchfish> Chetic, with latets firmware, shutdown -h now brings it in that low state.
[13:00] <booyaa> we've already had a report of someone getting data corruption because they haven't
[13:00] <booyaa> dutchfish: -h equivalent to halt and vica versa?
[13:00] <Chetic> dutchfish: does it stop reading/writing to the sd then?
[13:00] <Arch-MBP> isnt shutdown -h the same as halt?

[13:02] <Gadgetoid> Trieste: what are the particulars of your power supply, too?
[13:02] <Trieste> dutchfish: yes, i did

[13:06] <cmug> Your desktop powers the external HDD?

[13:06] <hetii> did some of you did performance test for Patriot sd card: PSF16GMCSDHC10 ?
[13:06] <cmug> Trieste: are you sure it gets enough power?
[13:07] <Arch-MBP> Trieste: if the system actually responds...then it???s a network issue perhaps
[13:07] <booyaa> hetii: http://elinux.org/RPi_VerifiedPeripherals#Benchmarks
[13:07] <booyaa> do kernel panics show up in messages or syslog?

[13:08] <cmug> yeah checking the /var/log/messages* would be the next step
[13:08] <hetii> booyaa: thx
[13:09] <Trieste> Hm, when I plug off the power to it, the OK and PWR led still remain lit up, until I also plug off the USB cable
[13:09] <Trieste> that probably shouldn't happen, right?
[13:09] <hetii> but without details about speed of this card :(
[13:09] <booyaa> Trieste: you're using it as a filer/nas just simple stuff like samba/nfs or full blown thing like openfiler(nas)?
[13:12] <Arch-MBP> Trieste: that???s normal
[13:13] <Trieste> booyaa: simple stuff, but it's not the only thing it does, I just use it as a NAS primarily - I also sometimes let it download something, could that utilize the usb hdd too much, causing the power the fail?
[13:13] <Trieste> Arch-MBP: oh, how come? Is that intentional?
[13:13] <booyaa> i wouldn't have thought so, i found apache/mysql when using wordpress sent mine into a death spiral but this is diff

[14:40] <deam> ah, good idea
[14:40] <deam> I was compiling something really large, should have been cross compiling on another machine instead but well..
[14:40] <NucWin> ^^^ im working on that
[14:41] <NucWin> just trying to figure out how to setup distcc and the toolchain in gentoo
[14:42] <deam> the kernel compilation guide has some good hints on setting up a cross compiler, did you see that?
[14:43] <deam> http://elinux.org/RPi_Kernel_Compilation#Gentoo_Linux
[14:44] <ReggieUK> not exactly the best methods for cross-compiling though
[14:44] <NucWin> i managed to cross compile the kernel on another machine but im now trying to get that machine to be the helper too the pi
[14:44] <NucWin> gentoo's documentation is quite vague
[14:44] <ReggieUK> don't get me wrong, they're valid
[14:44] <ReggieUK> but in general, you will have a lot of nightmares making everything work every time just from that vague description
[14:45] <ReggieUK> especially when it comes to things like configure etc.
[14:45] <NucWin> crosstool doesnt seem to make a bin directory for all the stuff it builds

[14:46] <ReggieUK> take a look at that
[14:46] <NucWin> so cant cheat by modifying distccd's PATH
[14:46] <ReggieUK> ukscone did that, it really should be on the wiki
[14:47] <ReggieUK> there are probably other methods around, it'd be nice to see how others are managing to cross compile effectively and what the best practices are from those that are currently doing it

[15:05] <Gadgetoid> Oh well, it's good news in a sense??? they obviously can't spool up production too much, or they'll meet up with demand quickly and end up overproducing
[15:05] <buZz> drogon: RS alone produces 10k a week
[15:06] <buZz> so farnell/e14 produces almost 20k a week
[15:06] <Gadgetoid> The Pi is also ??29.45 from Farnell before they even deliver it, vs just over ??30 delivered from RS...
[15:06] <NucWin> comes in better box from rs
[15:06] <NucWin> card box that is
[15:07] <friggle> does anyone have a picture of this amazing box?
[15:07] <Gadgetoid> NucWin: yay, extra cardboard!
[15:07] <NucWin> hey Gadgetoid its come in usefull for me
[15:07] <Crenn-NAS> I'm going to be ordering another RPi :D
[15:07] <Gadgetoid> Farnell also only have teeshirts in one size: "No longer available"
[15:07] <NucWin> can use it to carry 1 laptop hard drive and 2x rpi's
[15:07] <Crenn-NAS> My NAS (RPi ;D) needs to stay at home
[15:07] <Gadgetoid> NucWin: in a cardboard box!?

[15:11] <buZz> Gadgetoid: do you still have that box? :)
[15:11] <Crenn-NAS> Gadgetoid: 3rd?! Give us guys with only 1 a chance to order a 2nd ;P
[15:12] <Gadgetoid> Crenn-NAS: truethat, every man deserves a 2nd??? I have my Pi blog permanently installed on my 1st, though, and am having trouble switching OSes to test out my wrapped wiringpi libraries
[15:12] <Gadgetoid> So, good sir, I ordered a 2nd for the greater good!
[15:13] <Crenn-NAS> Gadgetoid: Hehe, I'm using this RPi for IRC currently
[15:13] <Crenn-NAS> Also as a web server and a NAS ;D
[15:13] <Gadgetoid> Crenn-NAS: I run a BNC on mine, plus Ruby Thin webserver??? and that's about it
[15:13] <NucWin> i ordered two incase i break one or want one while one is building packages lol
[15:13] <buZz> hehe
[15:13] <Gadgetoid> I also do all my library development, compiling and testing directly on the Pi, plus the repo management and updates to the WiringPi GitHub repo
[15:14] <buZz> i have my raspi just idle in a drawer
[15:14] <buZz> still want a second though
[15:14] <NucWin> farnell has hyinx ram and rs has samsung
[15:14] <Crenn-NAS> Got a 1.8" HDD laying around and ordered a USB case for it off flea-bay to give the RPi a little more storage
[15:14] <Gadgetoid> I say "directly", and mean "via SSH/SFTP", it's handy 'cos I can work on stuff from anywhere
[15:14] <NucWin> oops wrong way round its farnell with samsung
[15:14] <Gadgetoid> Crenn-NAS: you can get USB cases for 1.8" HDDs!? hmm??? I have one "lying around" in an old iPod

[15:20] <Tachyon`> I have a 1.8" ipod drive somewhere
[15:20] <Tachyon`> 30GB I think
[15:20] <Tachyon`> hadn't thought of using that with the pi
[15:21] <Crenn-NAS> Gadgetoid: Going to be designing a little NAS case with integrated power supply around the Pi and the electronics from that case
[15:21] <aaa801> whats the connection on those drives
[15:21] <Tachyon`> it's in a somewhat dead old black and white ipod
[15:21] <Tachyon`> it looked vaguely like het 2.5" connector as I recall
[15:21] <aaa801> oku
[15:21] <Tachyon`> but no idea what it is electrically
[15:21] <Tachyon`> I do know adapters to standard ide exist
[15:21] <Tachyon`> as I was looking at them
[15:22] <Tachyon`> so I suppoe to 2.5 and then a usb to ide adapter
[15:22] <Tachyon`> might even power it
[15:22] <Tachyon`> they only need 5, not sure what sort of current but if I can run a 2.5" external from USB...

[15:27] <booyaa> man i <3 i fixit!
[15:27] <booyaa> Crenn-NAS: heh
[15:27] <Tachyon`> hrm, this drive wants 3.3v
[15:28] <buZz> arent you glad Tachyon`
[15:28] <buZz> that the raspi just has a 3.3v power connector?
[15:28] <Tachyon`> it might be an odd interface though
[15:29] <Tachyon`> if all the logic is 3.3v too
[15:29] <ReggieUK> there is a 3.3v pin on the gpio if you need it
[15:29] <Crenn-NAS> buZz: It can't support the HDD
[15:29] <buZz> WHAT
[15:29] <Tachyon`> the supply is easy, just a regulator
[15:29] <ReggieUK> but really, do you want to be pulling moar powah through the polyfuses?
[15:29] <Crenn-NAS> ReggieUK: The 3.3V rail on the RPi only supports upto 40mA
[15:29] <ReggieUK> really?
[15:29] <buZz> oh lol
[15:29] <Tachyon`> Toshiba HDD1422 P
[15:29] <buZz> that not that much :)
[15:29] <ReggieUK> cos that doesn't look like a 40ma v-reg.....
[15:29] <buZz> i bet that hd needs at least 250mA
[15:30] <buZz> just add your own 3.3v regulator then
[15:30] <Crenn-NAS> ReggieUK: I believe that's 40mA for users to use
[15:30] <ReggieUK> not arguing, just wondering how you've come to the figure of 'only 40ma'
[15:30] <Crenn-NAS> elinux page I believe, let me dig it up
[15:30] <Tachyon`> hrm, says its' ATA100 here
[15:30] <Crenn-NAS> I could be wrong
[15:30] <Crenn-NAS> Tachyon`: It's a ZIF connector most likely
[15:31] <Tachyon`> it's a pin connector
[15:31] <Tachyon`> but the opposite gender to what you'd expect
[15:31] <ReggieUK> wouldn't be like the wiki to have wrong information on it, eh Crenn-NAS ;)
[15:31] <Tachyon`> looks more like a PCMCIA/CF connector than anything else
[15:31] <Crenn-NAS> And this Toshiba MK1214GAH wants 3.3V at 500mA
[15:31] <Tachyon`> ah, this is a MK2004GAL
[15:31] <Crenn-NAS> Tachyon`: Could be, earlier generations of iPod, you could replace the HDD with a CF card
[15:32] <Tachyon`> yeah, it's not just like a CF connector
[15:32] <Tachyon`> it IS a CF connector
[15:32] <Tachyon`> same pins/spacing
[15:32] <Crenn-NAS> Yep!

[16:01] <markllama> one of those "wouldn't it be cool" things
[16:01] <ReggieUK> booyaa, led0 is the OK led
[16:01] <booyaa> ReggieUK: when those classes are wired up (taking this from other systems) you can re purpose leds or in some cases silence them (i.e. you don't want the network led flickering every time a packet goes trough)
[16:01] <Neutron_> Gadgetoid: well actually I am going to use one pi as a little "bluetooth DUN to ethernet" device to provide internet connectivity to a laptop I have there.. the problem is just that the RPI will die while the laptop still runs on battery

[16:03] <ReggieUK> I believe the power led is directly wired to the 5v in or 3.3v reg

[16:19] <Gadgetoid> nid0: You pretty much have all your ports on one side already, then!
[16:19] <Gadgetoid> drogon: That thing *is* awesome
[16:19] <drogon> he moved the audio and compost video by extending them to the case, so hdmi, compost and audio were avalable.
[16:20] <Gadgetoid> I love his GPIO breakout and expansion boards idea
[16:20] <drogon> yea. I don't know right now if it's jus a one-off or if it's something e14 in the US is thinking of making...
[16:20] <reider59> woo hoo out for a meal tomorrow, nice change
[16:20] <nid0> Gadgetoid: partially yeah, tbh I wouldnt exactly need routine access to usb or ethernet either, so if they were internal that wouldnt be a problem

[16:21] <reider59> Local Farmers Arms has new management and chef, supposed to be good too. the last manager was miserable old so and so. Anyway, a group of us are going there, about 10-12 at least.
[16:22] <nid0> on the power supply i'm still trying to suss out if such as thing actually exists as a software-switchable powered usb hub
[16:22] <Gadgetoid> nid0: You mean to supply/remove power to each individual port?
[16:22] <nid0> and hopefully available cheaper than your typical ??200+ switchable rack pdu
[16:22] <nid0> Gadgetoid: yep
[16:22] <rcaskey> nid0, I paid $800 for mine :(
[16:23] <Gadgetoid> nid0: Just build your own cluster of 5v regs switched with transistors
[16:23] <drogon> you can get USB mains switches for under ?50 from what I remember... only 3 port though...

[16:24] * PiBot sets mode +v f8ba208e18
[16:24] <drogon> however, a microcontroller to control power to a number of USB ports wouldn't be hard to put together.
[16:24] <Gadgetoid> Can just let each Pi signal the microcontroller, so whatever Pi is up and running can reboot the rest in a round-robin fashion
[16:24] <drogon> I'd actually be tempted to use relays too to switch a good quality 5V supply just to save the losses via FETs, etc.
[16:25] <Gadgetoid> drogon: Haha, that would be better??? but I tend towards lazy/lossy :D

[16:28] <rcaskey> drogon, now see why I need 2 pis in my 1U :)
[16:28] <Gadgetoid> drogon: build your own, with electromagnets!
[16:29] <drogon> only 2 pi's in a 1U? Can't you fit about a dozen???
[16:29] <nid0> a potential out-of-the-box solution might just be some lightwaverf switchable sockets in a gang, that should total ??50 odd but is very bulky :<
[16:29] <drogon> microcontroller - uln2003's small signal relays (1Amp) and off you go...
[16:30] <rcaskey> drogon, the goal would be redundant services, not a ton of pis :)
[16:30] <rcaskey> plug in both power coords, plug in both network cables, make sure the switch was set to trunk the ports, and call it a day

[19:19] <Craig`> GriffenJBS: yeah I could do that and use the aux of my current radio but then i'd have visible wires, and i'd have to take the rpi out for theft reasons, with my idea it'd be hidden.
[19:19] <Syliss> should be easy-ish
[19:19] <GriffenJBS> either use your cig lighter as the plug or rip it apart and wire it to the 12V power in the car, behind the dash

[19:20] <GriffenJBS> Craig, just be careful, the pi is sensitive to power,
[19:21] <GriffenJBS> a good converter will handle the 12V no problem and the pi will be happy

[19:41] <pothibo> Hi, I don't own a raspberry pi yet but I'm planning to buy one to control my irrigation valves (landscaping) with it. Since I'm very new to this kind of technology, what kind of relay/controller do I need to hook it up to the raspberry pi? the Valves are running on 12v wires so I was thinking to use a sort of relay controller to open and close the valves. Any tips?
[19:43] <tech2077> theres many standard irrigation hose compatible solenoids for switching hoses on and off
[19:43] <tech2077> all you need to get the pi working with them is an interface board with some power mosfets to switch the solenoids on and off
[19:45] <pothibo> yeah exactly, I own the solenoid already, where my knowledge is lacking is what kind of interface board I should be looking at before buying the pi

[19:52] <mikey_w> Hmmm that striker needs 3 watts, lots of luck getting that from the 3v3 on the raspi.
[19:52] <pothibo> mikey_w: what do you mean? I'm a total newbie when it comes to this??? :(
[19:53] <mikey_w> I think you'll need an independent 12V source.
[19:53] <gordonDrogon> hi
[19:53] <mikey_w> 250ma times 12volts == 3 watts.
[19:54] <gordonDrogon> use uln2003's to drive a relay and use the relay to drive the solenoids.
[19:54] <mikey_w> The GPIO can switch the transistor.
[19:54] <pothibo> http://www.rainbird.com/landscape/products/valves/HV.htm this is the valves I own
[19:55] <gordonDrogon> yea- standard 24VAC supply to enable them. Use relays. Put drivers (e.g. uln2003's behind the relays)
[19:55] <gordonDrogon> you can power the relays from the 5V supply and they'll switch the solenoids.

[19:56] * PiBot sets mode +v Hexxeh
[19:56] <pothibo> so if I get this right. I have the pi opening/closing the relay, relay is connected to uln2003 and uln2003 is connected to a solenoid ?
[19:56] <mikey_w> Sorry just no simple answer.
[19:56] <pothibo> I'm not looking for simple answer, I'm looking for answer ;)
[19:56] <mikey_w> ok
[19:56] <gordonDrogon> pothibo, almost. the Pi is connected to the driver (uln2003) the driver switches the relay - the relay switches the 24vAC supply.
[19:57] <gordonDrogon> think of it as a series of amplifiers.
[19:57] <GriffenJBS> why not use a diac?

[19:57] <GriffenJBS> think transistor for AC
[19:57] <mikey_w> It is doable. Have fun.
[19:57] <gordonDrogon> The uln2003 amplifys the Pi's puny signal to that which will drive the relay and the relay amplifys the uln2003 output to drive the solenoid.
[19:57] <GriffenJBS> or solid state switch for AC
[19:58] <mikey_w> Relays will not require a heat sink.
[19:58] <gordonDrogon> You can get some nice opto isolated SS switches, yes. usually more expensive, but I use them to switch mains power.

[19:59] <gordonDrogon> keep it simple. less to go wrong in this sort of environment.
[19:59] <mikey_w> Maye the PI can trigger an electrical shock to remind you to throw a switch?
[19:59] <mikey_w> hmmmm.
[19:59] <gordonDrogon> well if you want 50 of them :)
[20:00] <pothibo> I'm talking about the product ;) not the price/amoutn
[20:00] <gordonDrogon> Actually, you probably want the ULN2803A variant.
[20:00] <gordonDrogon> It has built-in diode protection for driving relays & motors.
[20:00] <gordonDrogon> Or a Gertboard - it has 8 of them on-board...
[20:00] <pothibo> I see
[20:00] <gordonDrogon> er, 7.
[20:01] <pothibo> 8 what? relays?
[20:01] <mikey_w> Using several GPIO pins and a decoder you can make a dancing sprinkler system.

[20:04] <mikey_w> experiment with driving leds.
[20:05] <pothibo> yup I guess that's what I'll do
[20:05] <pothibo> once I have leds working, I'll be able to add on buffer via ULN2803 and make my solenoids work
[20:05] <pothibo> right? :P

[20:18] <plugwash> the Pi is low power compared to a desktop PC but it's very power hungry compared to microcontrollers etc
[20:19] <gordonDrogon> 2000mAh per cell, so in series that's per stack - at a conservative 200mA for an idle Pi, that's 10 hours..
[20:19] <plugwash> and running it off batteries for long periods means you basically have to resort to big lead acid batteries
[20:19] <markllama> and/or big solar cells
[20:19] <markllama> plus Pb batteries...
[20:20] <plugwash> gordonDrogon, if you were stupid enough to use a linear regulator yes
[20:20] <gordonDrogon> plugwash, that's bare numbers without a regulator.
[20:20] <gordonDrogon> you still have 2000mAh capacity in the stack.
[20:20] <gordonDrogon> unless you parallel them up.
[20:20] <GriffenJBS> rcaskey: what are you trying to run pi on batteries for?
[20:21] <plugwash> gordonDrogon, well you can't really run the Pi off batteries without a regulator since the voltage variation is far too wide
[20:21] <gordonDrogon> plugwash, I know, so 200mA is conservative - I just used it to make the calculation easier.
[20:21] <plugwash> and if you are going to use a regulator it may as well be a switcher
[20:21] <GriffenJBS> it's possible to have the pi power on, run fast (faster than uC), then power off until needed again, that will make it last a while, but only if you have a good queue of work
[20:21] <gordonDrogon> has anyone actually measured the current consumption of a Pi?
[20:22] <GriffenJBS> gordonDrogon: depends too much on what you have plugged in and what you are processing
[20:22] <GriffenJBS> from idle of about 0.2A to max of ... ? 0.5-0.75
[20:23] <plugwash> you can reduce the power consumption a bit more by removing the 3.3V regulator and using two switchers to independently power the 5V and 3.3V lines
[20:23] <plugwash> http://www.bitwizard.nl/wiki/index.php?title=Reducing_power_consumption_of_a_raspberry_Pi
[20:23] <gordonDrogon> it ought to be much less than 0.75 amps - I'd guess since the USB is allowed ~300, then out of the 700mA allowed you have a max of 400mA for the rest of it.
[20:24] <gordonDrogon> a friend of mine put this together a while back: Last page has the numbers: http://stuarthalliday.com/reviews/alkaline-batteries-reviewed-part-7/
[20:25] <rcaskey> GriffenJBS, well if you were going to use it to water a greenhouse...
[20:25] <Syliss> what about rechargeables?
[20:26] <gordonDrogon> about the same as the best alakaline/lithiums, but a lower voltage - typically 1.2, so you might need more of them to get the minimum voltage needed for the regulator.
[20:26] <GriffenJBS> on a timer? use a uC, they idle a crazy low power and have plenty of umph to do that, besides you'll need external power to run the system (solenoid)

[20:28] <gordonDrogon> I'm looking at powered a Pi from a sealed lead acid, but it's proving to be somewhat troublesome - 6V is really too low to drive a 5V regulator, even a posh switching one, and I really need 6V anyway to drive the motors I'm driving, so 12V is too big. It's a bit of a piggy to work out.
[20:28] <rcaskey> yeah, I guess tapping the 24v might be the way to go
[20:29] <plugwash> gordonDrogon, a SEPIC converter would do it
[20:29] <plugwash> but they are relatively complex
[20:29] <GriffenJBS> gordonDrogon: what?! switching regs can basically handle it all, as long as you have the wattage, they'll produce the output

[20:42] <ReggieUK> can you use a chopper driver?
[20:42] <ReggieUK> something like the easydriver?
[20:43] <plugwash> national semiconductor's webbench tool will design you a SEPIC converter that will go from 4-6V in to 5V out
[20:43] <plugwash> but it's relatively complex to actually build
[20:43] <ReggieUK> then you just need to adjust a pot to limit the current at the given voltage
[20:44] <gordonDrogon> I'm sort of hoping to be lazy and not have to actually build the regulator, but if I have to ...
[20:45] <gordonDrogon> I don't mind actually buying one, but I've not found a suitable device yet.

[22:15] <gordonDrogon> with a regulator, I presume...
[22:15] <buZz> but yeah 11.9v now, they are a bit high
[22:15] <buZz> that display is a regulator
[22:15] <buZz> it also measure and displays ampere :P
[22:16] <gordonDrogon> ok - it's not connected to Pi then?
[22:16] <buZz> nope
[22:16] * dirty_d (~andrew@ has joined #raspberrypi
[22:16] <dirty_d> whats new in the world of raspberry pi?
[22:16] <buZz> wait, i'll show the ebay link
[22:16] <buZz> http://www.ebay.com/itm/12V-to-5V-2A-Voltage-Regulator-DC-DC-Buck-Converter-Voltmeter-Ammeter-RED-LED-/180872383821
[22:18] <dirty_d> wooow, people are buying raspberry pis on ebay for > $60
[22:18] <f8ba208e18> I'm hardly surprised. The waiting time is quite overwhelming
[22:19] <dirty_d> how can it still be so long if theyre making 4000/day
[22:19] <f8ba208e18> poor shipping management, perhaps. I couldn't tell!
[22:20] <gordonDrogon> that's almost exactly what I want... if only it was in the UK.
[22:20] <f8ba208e18> I'm still waiting for mine, about 7 weeks to go. quite tired of waiting
[22:20] <phire> I just got mine yesterday

[22:21] <dirty_d> but i did pre-order the first day i could
[22:21] <buZz> phire: farnell is shipping almost 2500 a day
